You are driving in a two-lane one-way street and try to overtake the vehicle driving in front of you. The main risk in deviating to the left is:

1. The crossing of an unbroken separation line.
2. An incoming vehicle driving in your opposite direction might appear on the lane to your left.
3. Correct answer: Disturbing a vehicle driving in the left lane.
4. Disturbing a vehicle driving behind you on your lane.

WhyOn a one-way road with two lanes you move left before overtaking, and the danger is a vehicle already driving in the left lane.
